CN203864227U - Gel pen capable of being repeatedly used by adding ink - Google Patents

Abstract

The utility model discloses a gel pen capable of being repeatedly used by adding ink. The gel pen comprises a pen cap, a pen point and a pen rod, and is characterized in that the gel pen further comprises a rubber plug arranged on the inner side of the rear end of the pen rod, a capillary tube with one end inserted and fixed in the rubber plug and the other end located in a cavity of the pen rod, and elastic ink adding holes formed in the rubber plug and located beside the capillary tube. The capillary tube is half of the pen rod in length. According to the gel pen of the structure, ink is added in the pen rod through the ink adding holes in the rubber plug by inserting an ink tank needle after the ink is used up, and the gel pen can be used again. The gel pen has the advantages that the ink can be added repeatedly, ink adding quantity is large, the ink is convenient to add, hands can not be stained, the gel pen does not need to be wiped by tissue, and the advantage of repeated ink adding of a foundation pen and the advantage that the gel pen can not leak ink are combined; manufacturing is simple, cost is low, and the environment is protected. Ink adding quantity in one time is equal to the quantity of ink of 5 common gel pen cores, and therefore the number of written characters is about 5 times that of the common gel pen.

Description

Can repeat to add the gel ink pen that China ink is used

Technical field

The utility model relates to a kind of writing with pen, especially gel ink pen.

Background technology

The gel ink pen generally using is at present all by pen core, to add a shell to make.Pen core is made too complicated, can not repeat to add China ink, and quantity of ink is few, is finished and abandons, contaminated environment.

Utility model content

The purpose of this utility model is to provide a kind of repetition and adds the gel ink pen that China ink is used, and economizes on resources and protection of the environment.

For achieving the above object, the technical solution of the utility model is:

Repeat to add the gel ink pen that China ink is used, it comprises the pen cap, nib and penholder, characterized by further comprising:

Be arranged on the rubber stopper of described penholder rear inside;

One end is inserted and to be fixed in the middle of described rubber stopper, the other end aerial capillary in penholder;

Be arranged on described rubber stopper capillary elasticity ink-filling hole on one side.

Half that described length capillaceous is penholder.

The gel ink pen of above structure by the ink-filling hole on rubber stopper, inserts ink tank needle tubing toward refilling in penholder after its ink is finished, and pen can be used again.Advantage of the present utility model is:

1, can repeat to add China ink, add China ink amount large, add China ink convenient, not dirty hand, without paper handkerchief wiping, existing fountain pen can repeat to add black advantage, has again the not advantage of ink leak of gel ink pen;

2, manufacture simply, cost is low;

3, environmental protection.

Accompanying drawing explanation

Fig. 1 is sectional structure schematic diagram of the present utility model;

In the drawings, nib 1, the pen cap 2, penholder 3, capillary 4, rubber stopper 5, pressure type ink tank 6, elasticity ink-filling hole 7.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail;

Shown in Fig. 1, it is sectional structure schematic diagram of the present utility model; As we know from the figure, nib 1 lower end that be fixed on penholder 3 the same as common gel ink pen nib.The rubber stopper 5 of establishing in penholder 3 rear inside, the centre that is fixed on described rubber stopper 5 is inserted in one end of capillary 4, and the other end is interior aerial in penholder 3.On described rubber stopper 5, one side of capillary 4 is provided with elasticity ink-filling hole 7.Described elasticity ink-filling hole 7 is to be through on resilient rubber stopper 5 with pin, extract after pin due to the concrete elasticity of rubber, hole can be blocked loosely again, be that Ink-Filling Needle Tube inserts can automatic-sealed after adding China ink and extracting, so this hole dots in the drawings, make the ink in penholder 3 be difficult for spilling, and the convenient insertion of Ink-Filling Needle Tube next time.The pen cap 1 is the same with common gel-ink pen cap, the main protection nib that rises, and sealing nib, prevents the effect that neutral water oozes out.Penholder 3 is once injection molded by plastics, 12 centimetres of left and right of length.The length of described capillary 4 is half of penholder 3, plays UNICOM's penholder 2 inside and outside, makes the effect that within is ventilative.Capillary 4 is generally less than the tubule of the material such as plastics, glass, stainless steel of 0.1MM for aperture.

Adding black process is:

In pressure type ink tank 6, install Neutral writing ink, by tank needle tubing, insert in the elasticity ink-filling hole 7 of rubber stopper, toward the interior refilling of penholder 3, refilling be highly 3 centimetres more applicable, then extract tank needle tubing, ink-filling hole 7 automatic-sealeds.So highly can make Neutral writing ink self gravitation little, nib ink bleed is very little, the same with common pen core.Due to capillary 4 in the aperture of penholder 3 inside in the center of penholder, when states such as pen is inverted, is kept flat, upsets, inner Neutral writing ink all can not flow out, and remains ventilative state in penholder 3.After adding China ink, get rid of pen, allow Neutral writing ink soak full nib 1, just can be as common gel ink pen smooth and easy writing.Because this inner space is large, ink does not form bubble.Once adding the China ink amount that black China ink amount is equivalent to 5 of common refill of gel-ink pens, is 5 times of left and right of common gel ink pen thereby make to write number of words.

Claims (2)

1. can repeat to add the gel ink pen that China ink is used, it comprises the pen cap, nib and penholder, characterized by further comprising:

Be arranged on the rubber stopper (5) of described penholder (3) rear inside;

One end is inserted and to be fixed in the middle of described rubber stopper (5), the other end aerial capillary (4) in penholder (3);

Be arranged on described rubber stopper (5) upper, capillary (4) elasticity ink-filling hole (7) on one side.

2. according to claim 1 repetition adds the gel ink pen that China ink is used, and it is characterized in that:

The length of described capillary (4) is half of penholder (3).
